` AFFARATUs FOR MAoFRA'r-INGWORT.

To all whom it may concern: l f

Be it known that I, ROBERT HOFFMANN a subject of the King of Prussia, and resident of Ortelsburg, Germany, have invented new and useful Improvements in Apparatus for llfaceratingWor't, of which the vfollowing isy a specification.

In macerating they wort in making beer the sparging water has hitherto been poured on to the wort by means of a rotary sprayer spraying over or sparging the wort.. As the sparging water falls from a certain height on to the surface of the wort it is not only impossible to avoid unintentionally mixing the wort with the sparging water,'but the latter is also undesirably cooled. Both disadvantages thus involve a loss of yield from the grain and thus mean an incomplete' working. K i

Now as compared with the ordinary apparatus for maceration this invention consists in the sparging water not being, allowed to fall from a height on to the surface of the wort but being introduced in layers on to the surface of the wort, so that the gra-in during -maceration is slowly compressed by the sparging vwater and does not mix-thereV with.

This improved apparatus consists in other'` words in the sparging water being allowed to flow on to the wort in a continuous stream without first having to fall through the air'- on to the surface of the wort.

By means of this invention not only is the considerable cooling of the sparging water avoided which takes place by the splashing the dish. The dish may be provided withfloats in order that it may be always main- 'tained floating at a uniform level." 'These floats hold the edges of thedishsome milli.- meters below the surface of the wort or the spar-ging water. For tlie introduction of the taining the dish as far asposs'ible in the middle ofthe vat.

`:and Fig. a2, a plan view. y 1 -V This'apparatus consists of a dish a, for

instance of sheet aluminium, to which a. number of A floating bodies 1b, i. (for instance Yfour as shown in the drawings), kare attached. The 'connection between the dish L and the floating bodies?) is preferably adjustably ar#` ranged, by each lfloatI being carried by a bar "In the drawing z-Figure 1 is a section;v

adjusted by hand screws c in its distance from and the height above the edges of the dish. It is thereby possible to give the edge of the dish any desired position Abeneath the levelof the liquid; It usually suffices for the edge of the dishto be about lmillimeters from the level of the liquid. The distributing dish a.

always maintains its level when once adi admitted. f Some cylindrical rings d or like impediments which prevent a too rapid discharge ofthe sparging water from thefeed justed even when a full supply of waterlis pipe e which discharges at the middle of the c.

Jdishmay also be provided which further insure afuniform distribution ofthe water over the `entire periphery of the dish.

`funnel or guide nozzle]c is provided in the 'middle lof the dish which funnell is per-fv forated at its lower .edge and also is arranged to receive the feed pipe e. l,As this pipe c can be easily 'fiXedto the edge of the vat or ats'ome other place, it also serves for yretaining the floating dish a in the middle of the vat or in some other'desired position. The floating dish may alsoy be made in a Vform differing fromthat--shown in the drawings, i For instance the hollow floating bodies maybe replaced vby'wooden floats. Gal-` vanized sheet irony may also be employed as Y' material for the dish aswell as for the floats. I declare that what l claim is 1. An apparatus for n, macerating wort,

comprising in combination, means for conveying the sparging water to and discharg-` ing the same closely adj acentto the surface of the wort, and a plate Asuspended bythe y,

wort for receiving said sparging water.

Y2. An apparatus ffor macerating .wort

comprising in combination, means for con- '.veying the sparging water thereto and dis- 'charging the same closely .adjacent the suryface of the wort, and a floating plate by the zwort for receiving the sparging water, sub-VK stantially Las described;

53. An `apparatus for' maceratmg wort comprising in combination, means conveying the sparging Water to and discharging the same closely adjacent the surface of the Wort, a plate for receiving the sparging Water, and floats on Which said plate is suspended.

4l. An apparatus for macerating Wort comprising in combination, means conveying the sparging Water to and discharging the same closely adjacent the surface of the Wort, a plate for receiving the Wort, and floats suspending said plate below the surface of the Wort.

5. `An apparatus for macerating Wort comprising in combination, means conveying the sparging Water to and discharging the same closely adjacent to the surface of the Wort, a plate provided with ribs for receiving the Wort, and floats adjustably mounted upon said plate for suspending the same bcloW the surface of the Wort.

In testimony, that I claiin the foregoing as my invention, I have signed my naine in presence of two Witnesses, this 19th day of April, 1911.
